Ezekiel 24:27

27On that day 24:27 At the beginning of Ezekiel’s prophetic ministry (see 3:26, 27; 33:22) God told him he would be mute except when he was speaking a divine prophecy.your mouth will be opened to him who escaped, and you will speak and no longer be mute. In this way you shall be a sign to them, and they will know [without any doubt] that I am the Lord.’ ”
